A1.5/F1.5 X3KA Map - ERROR:baspw:96 - The physical constraint resolution process is unable to resolve all placement constraints
描述
ERROR:baspw:96 - The physical constraint resolution process is unable to resolve all placement constraints When you try to lock p13 on 3130a-pc84 you get this error message. p13 is the tclkin/io pin and when you try to use it as a normal i/o map puts a prohibit constraint for that site in the pcf file and par cannot handle that and you get this error message.
解决方案
1
The resolution as of now is to remove the prohibit constraint from the pcf file.
2
In F1.5, win NT, same error occured in PAR. This is due to duplicate pin constraints in the UCF file.
